SrCa maxima matched to winter minima (August 15) and fine tuned using UCa.
Off-cut of coral section used for record dated July 2022. Date sample taken from top of off-cut section and assumed to match youngest year of the record. See GBRCD Appendices.
LA-ICP-MS methods as per Lewis et al. (2012) (laser 50 x 500 μm rectangle on the coral surface). Data smoothed to reduce data volume with 10-point running mean and then a further 10-point mean. No analytical precision data available.
Barium/Calcium. A secondary Ba/Ca measurement for laser ablation datasets. This is a measure of the total Ba/Ca using the count intensities of the Ba138 isotope.
Off-cut of coral section used for record dated July 2022. Date sample taken from top of off-cut section and assumed to match youngest year of the record. See GBRCD publication appendices.
Barium/Calcium. For laser ablation datasets this is a measure of the total Ba/Ca using the count intensities of the Ba137 isotope.
A measure of the total Ca/Ca ratio using the count intensities of the Calcium48/Calcium43 isotopes.
Distance measured from outer edge of coral or core.
